Henna-hooded Foliage-gleaner
Clibanornis erythrocephalus
Attractive foliage-gleaner found in dry and semi-humid forest in western Ecuador and northwestern Peru. Plumage is brown with an orange to reddish hood and chestnut wings and tail. Usually stays quite low and sometimes hunts for food on the ground. It stays in dense cover, and is easier to see in the dry season when many trees and bushes lose their leaves. Song is a short burst of odd, nasal notes repeated every several seconds. Threatened by habitat loss.
识别特征
The henna-hooded foliage-gleaner is about 21 cm (8.3 in) long and weighs about 48 g (1.7 oz). It is a large, boldly-patterned foliage-gleaner with a thick, slightly decurved, bill. The sexes have the same plumage. Adults of the nominate subspecies have a unique henna (orange-rufous) head, neck, wings, and tail. Their back is brownish olive. Their underparts are mostly pale brownish gray with a rufous crissum. Their iris is variable from yellow to gray-brown, their maxilla gray or blackish gray, their mandible whitish or horn with a dusky end, and their legs and feet olive or gray. Subspecies C. e. palamblae is a paler rufous where the nominate is henna, and has a grayer (less brownish) back and a paler buff breast and belly.
分类信息
The henna-hooded foliage-gleaner has previously been placed in genera Automolus and Hypocryptus but genetic data place it firmly in Clibanornis. It has two subspecies, the nominate C. e. erythrocephalus (Chapman, 1919) and C. e. palamblae (Zimmer, JT, 1935).

分布与栖息地
The nominate subspecies of the henna-hooded foliage-gleaner has a disjunct distribution. One population is found in west-central Ecuador's Manabí and Guayas provinces. The other is from far southern Guayas and Auzuay provinces south through El Oro and Loja into Peru's extreme northwestern Department of Tumbes. Subspecies C. e. palamblae is found further south, in the Peruvian departments of Piura and Lambayeque. The species inhabits deciduous and semihumid forests and woodlands, mostly on the lower slopes of the west side of the Andes. It favors areas with many species of Malvaceae, the mallow family. In Ecuador it mainly occurs between elevations of 400 and 1,800 m (1,300 and 5,900 ft) and in Peru between 400 and 1,500 m (1,300 and 4,900 ft).

行为
The henna-hooded foliage-gleaner is a year-round resident throughout its range.<p>The henna-hooded foliage-gleaner's diet has not been studied but appears to be terrestrial invertebrates; isopods are a known component. It forages singly and in pairs and often joins mixed-species feeding flocks. It hunts its prey on and near the ground, noisily flicking aside leaves and probing among leaf litter, clusters of dead leaves, and vine tangles.<p>The henna-hooded foliage-gleaner's breeding season is from January to May. Both adults excavate a burrow in a shaded earthen bank and build a nest of rootlets and other fibers in a chamber at its end. All known clutches have been of three eggs. The incubation period is 16 to 19 days; the time to fledging and details of parental care are not known.<p>The henna-hooded foliage-gleaner's song is far-carrying, "a persistent, staccato churring, 'kree-kruh-kruh-kruh-kruh-kruh-kruh-kurr' with [an] odd, mechanical-sounding quality". It also has a distinctive call, "a short, sharp, high note".

Tickell's Leaf Warbler
Phylloscopus affinis
Brown-and-yellow leaf warbler without a wingbar. Breeds in high-altitude areas, in open areas with low vegetation. Winters at lower elevations, including throughout the Indian Subcontinent south of the Himalayas, where it is most abundant in shrubbery in the northeast Indian plains and in the high Western Ghats. Resembles Sulphur-bellied Warbler, but has a yellower cheek and underparts, and shows little contrast between the eyebrow and the throat. Tickell’s spends less time on or near the ground than Sulphur-bellied, tends to flock, and often participates in mixed-species foraging flocks.
White-throated Swallow
Hirundo albigularis
A swallow with a small rufous patch on the forehead and a diagnostic complete steel-blue breast band which forms a white throat patch. This migrant breeds in South Africa in the Austral summer, September to April, and spends the non-breeding period (May to August) in south-central Africa. It prefers foraging in pairs or groups, sometimes with other swallow species, in grassland, light woodland, and floodplains, and is often seen perching on fences or on posts near water.
New Zealand Pigeon
Hemiphaga novaeseelandiae
Large pigeon endemic to New Zealand with distinctive blue-green iridescent plumage, white belly, and red eye. Makes conspicuous display flights in breeding season; often seen feeding on heavily fruiting trees or fresh leaves and flower buds in spring. Widespread where food is available. Only emits soft “oo” calls, but note distinctive wingbeat sound, especially when alighting or taking off. Chatham Island Pigeon, the only similar species, is larger and confined to Chatham Islands.
